TRUCKLE  , a verb meaning to submit servilely or fawningly to another's bidding, to yield in a weak, feeble or contemptible way . The origin is the " truckle

bed," a small bed on wheels which could be pushed under a large one . In early times servants or children slept in such beds, placed at the foot of their masters' and parents' bed, but the name first appears as a university word, and was derived direct from Latin trochlea, a wheel or pulley-block, Greek Tpoxos, wheel (rpEXeiv, to run) .
